Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** and thanks for your question.
Check fuse 10 in the interior fuse box, it should have power at all times. If power OK then remove steering column trim shrouds to access multi function turn signal switch. Check for power at the dark blue/orange wire, should have power at all times. Also check for any wires pulled out of connector there, very common for wire pullout from connector. If good power on that wire then turn on high beams and check for power at the light green black. If no power and wires not pulled out then replace multi function switch. If power than you have an open circuit between that wire and fuse 30.

Sorry I just read that fuse 30 had voltage, thought it just said fuse good, so disregard above
You have an open circuit after fuse 30. You will need to locate connector C234 and check for power at the light green/black wire at that connector with the high beams on. C234 is located on the drivers side cowl in the engine compartment. Click link below for diagram.
If good power there then you will need to locate connector C162 and check for power on that same wire with the high beams on. C162 is located near the battery, diagram at link below.
Just checking in to see if you need further assistance. If you are satisfied with your answer, please respond with "I am satisfied with your answer" or "your answer helped". I will then forward that response to the site admin so my feedback can be updated.
Yes voltage with high beams on, that's the wire light green/black goes all the way to the bulb connector after splices. The high beam indicator is powered from splice after C162. The splice is in the harness that runs behind the grill near the hood latch.
Actually the buzzer is a separate issue, the warning buzzer module receives its input off the parking lamp circuit which is the brown wire coming out of the headlamp switch.
Ok sounds good. The buzzer is shared with the key, seatbelt and headlamps. Center of dash.
18 seems a little thin for the circuit load, I would use at least 14 if not 12. The other wire should be for the high beam indicator. Glad you found it!
Your very welcome!
Very busy at work right now, I will investigate and reply asap
No worries, each component, seat belt, key,lights supply an individual ground to the buzzer module. I would locate the module and see if any of the wires are cut first. Wiring diagram at link below. for the ABS, there is a light green/black wire and a red/pink wire that passes through C234 for the abs self test connector, you want to make sure neither of these wires is touching ground as it will kill the speed sensor signal to the abs module. There is also a dark green/yellow wire that passes through C234 and provides power to the low fluid sensor in the master cylinder, and finally a light blue/pink wire that supplies power to the abs module from fuse 1 in the interior fusebox.
Correct I just double checked. high beams is pin 37, abs is pin 55. Pinout at link below.
